Yes, Kai's patch (see URL) works for -fwhole-program as well as LTO :)

Yes, it certainly does, in fact it omits to compile any definition for 'foo'
whatsoever!

But isn't this the expected behaviour of using '-fwhole-program' on something
that is not the whole program?  I'm not sure if the option is supposed to be
suitable for use when building a shared library, I'll ask on the mailing list.

Consensus seems to be that this is indeed how it's meant to work, but that
figuring out which are the externally visible functions and marking them
automatically would be a nice enhancement that would make the -fwhole-program
option work on libraries, so I think we should do it.
